Abstract
Methods and systems for rapidly rolling back and retrying a data migration between a first and a second storage system. In one embodiment, upon receiving a request at a provisioning manager to perform a rollback of a first data migration, the first storage system merges, to a baseline dataset, a first incremental dataset received by the second storage system after the first data migration. In another embodiment, upon receiving a request at a provisioning manager to perform a retry of the data migration, the second storage system merges, to the data received by the second storage system during and immediately after the first data migration, a second incremental dataset received to the first storage system after performance of the rollback. Throughout the migration rollback and retry, the data of the baseline dataset, first incremental dataset, and second incremental data set is made available to the client.
